The Department of Defense (DoD), General Services Administration (GSA), and National Aeronautics and Space Administration (NASA) published a final rule, effective September 10, 2021, that finally updates the methodology to calculate compliance with the limitations on subcontracting.

The NDAA:  Section 1651 of the National Defense Authorization Act (NDAA) for Fiscal Year (FY) 2013 (15 U.S.C. 657s) revised and standardized the limitations on subcontracting, including the nonmanufacturer rule, that apply to small business concerns.

Implementation in SBA’s Regulations:  The Small Business Administration (SBA) implemented section 1651 of the FY 2013 NDAA in a final rule published at 81 FR 34243 on May 31, 2016, which became effective on June 30, 2016.

Proposed Rulemaking to Update the FAR:  DoD, GSA, and NASA published a proposed rule at 83 FR 62540 on December 4, 2018, to implement regulatory changes made by the SBA.

Key Set of Changes Made to the FAR:

The final rule updates the methodology for complying with the limitations on subcontracting.  FAR 19.505 and FAR clause 52.219-14 provide that a small business concern subject to the limitations on subcontracting will pay no more than a certain percentage of the amount paid by the Government for contract performance to subcontractors that are not similarly situated entities.  As with 13 C.F.R. § 125.6, the relevant thresholds are set as follows:

  • For a contract assigned a services NAICS code, the small business concern must not pay more than 50% of the amount paid by the Government for contract performance to non-similarly situated subcontractors;
  • For a contract assigned a NAICS code for supplies or products (other than a procurement from a nonmanufacturer), the small business concern must not pay more than 50% of the amount paid by the Government for contract performance, excluding the cost of materials, to non-similarly situated subcontractors;
  • For a contract assigned a general construction NAICS code, the small business concern must not pay more than 85% of the of the amount paid by the Government for contract performance, excluding the cost of materials, to non-similarly situated subcontractors; and
  • For a contract assigned a special trade contracting NAICS code, the small business concern must not pay more than 75% of the amount paid by the Government for contract performance, excluding the cost of materials, to non-similarly situated subcontractors.
